The invention provides an overflowing valve of a quantitative container for a water treatment quality-control terminal, belonging to the field of chemical test instruments and being used for solving washing problems of the quantitative container. The overflowing valve of the quantitative container comprises a valve body matched with an overflowing hole in a quantitative container wall and is characterized in that: the valve body comprises a solenoid valve; a fixed body of the solenoid valve is connected with a bracket which is arranged on the quantitative container; a movable body of the solenoid valve is horizontally connected with a plug which is matched with the overflowing hole in a sealed manner; and the movement direction of the plug is same as the axis direction of the overflowing hole. According to the invention, a plug structure which is controlled by the solenoid valve is adopted for the overflowing valve and the problem of inner residual liquid does not exist, so that the quantitative container can be effectively washed.
Description
technical field [0001] The invention relates to a chemical test instrument, in particular to a quantitative container overflow valve for a water treatment quality control terminal to ensure the accuracy of water quality monitoring data. Background technique [0002] With the improvement of national environmental protection policies and the strengthening of management, automatic water quality monitoring has been widely used in actual monitoring. How to ensure the long-term operation of the automatic water quality monitoring system and the validity of data has always been a hot topic. The maintenance and quality control of the water quality automatic monitoring system is the key to determine the accuracy, precision, representativeness, completeness and comparability of the monitoring data. [0003] Generally speaking, the automatic water quality monitoring system itself has the function of automatic cleaning, but if the water quality is poor and the water contains a large amou...
